The idea
Probabilistic reasoning buys graded, calibrated, always-available belief — and pays in numbers that must come from somewhere: counts, experts, or learning, each with its own failure modes.
In practice
A wrong prior does not crash the calculus; it flows through it, emerging as a confident posterior with nothing visibly amiss.
Where people slip
The arithmetic guards belief's form; the content stays as good as what was written down.
